10 by 800 thresholds I underestimated this workout. I thought, at the start, that we were going way too slow but by the end my legs felt like lead. I get better cardio with a half hour peloton but the cardio isn’t the point. I started my watch late on the 4th one and that’s why i thought i was in the first group. Other than that one, my heart rate was consistently 52-54 (156-162) Doubling this evening
